<a name="index-expressions"></a>
<a name="index-arithmetic"></a>
<p>The syntax for expressions in the linker script language is identical to
that of C expressions.  All expressions are evaluated as integers.  All
expressions are evaluated in the same size, which is 32 bits if both the
host and target are 32 bits, and is otherwise 64 bits.
</p>
<p>You can use and set symbol values in expressions.
</p>
<p>The linker defines several special purpose builtin functions for use in
expressions.
